Highlights

6
  • Achieved an industry-leading NPS score of 45, over 20% higher than the next closest competitor.

  • Delivered 217,000 postpaid net account additions in Q1, representing a 6% year-over-year increase.

  • Reported strong postpaid ARPA growth of 3.9% year-over-year.

  • Increased core adjusted EBITDA by an industry-leading 12% year-over-year.

  • Returned $6 billion to shareholders in Q1 through dividends and share buybacks.

Concerns

2
  • Equipment sales versus equipment revenue produced a greater loss by a few hundred million dollars year-over-year.

  • Q2 postpaid ARPA growth is anticipated to be lower, near 2% year-over-year, due to prior year rate plan optimizations and the dilutive effects of recent acquisitions (UScellular, Metronet, Lumos).

Deals & partnerships

GoNetSpeed, Greenlight Networks, i3 Broadband acquisition $2.7 billion investment across the 2 JVs

T-Mobile is entering into two additional JVs with leading infrastructure partners to acquire these fiber assets. The strategy focuses on local scale and pure-play fiber assets, not chasing homes passed numbers.

SpaceX partnership

Partnership for Direct to Cell service, aimed at ending dead zones. Usage primarily in national parks. Seen as a complementary product, distinct from broadband. T-Mobile also partners with SpaceX for Super Broadband, a B2B product combining 5G FWA with satellite backup.

Figure AI partnership

Connecting T-Mobile's 5G advanced network to Figure AI's F03 humanoid robots to enable seamless and reliable connectivity. This collaboration explores how the network can support the evolution of physical AI and edge inferencing.

Risks & headwinds

Competitive intensity in postpaid market Q1 FY26

January was 'particularly competitive and particularly heavy in one-dimensional competition based on subsidies.'

Mitigation:Focus on differentiation through best network, value, and experience; thoughtful promotion design based on customer lifetime value (CLV).

Dilutive effects of acquisitions on ARPA Q2 FY26

Q2 ARPA growth expected to be near 2% year-over-year, lower than Q1.

Mitigation:Anticipated and factored into full-year ARPA guidance of 2.5%-3%; underlying organic ARPA growth is stronger.

Increased loss from equipment sales Q1 FY26

Equipment sales versus equipment revenue produced a greater loss by a few hundred million dollars year-over-year.

Mitigation:Attributed to a larger customer base and higher acquisitions/upgrades; device promotions are designed to drive switching and upgrades on a smart, value-accretive CLV basis, often linked to premium device plans that drive ARPA increases.

Q&A highlights

Can you comment on reports of a potential merger with Deutsche Telekom, including the logic, logistics, and potential premium for US shareholders?

Management does not comment on market rumors or speculation. However, hypothetically, any such transaction would require a separate approval process by disinterested shareholders, often referred to as a majority of the minority.

“As a matter of policy, we don't comment on market rumors or speculation, nor is there anything specific to comment on anyway. However, the article has raised a lot of questions inbound on governance. We've looked into the governance. And what I've been told is hypothetically, if someone were to ever consider such a transaction reported in the article, that would specifically require a separate approval process by disinterested shareholders, what many of you refer to as majority of the minority.”

Detailed narrative

Strategic Differentiation and Market Penetration

T-Mobile's strategy of widening differentiation, offering the best network, value, and experience, is driving significant growth. The company achieved an industry-leading NPS score of 45, more than 20% higher than its closest competitor. This differentiation is attracting network seekers and enabling T-Mobile to gain market share, particularly in smaller markets and rural areas where it holds a 24% share of households and has led postpaid switching for 12 consecutive quarters.

Advancing Network and AI Capabilities

The company is continuously pushing the boundaries of its nationwide 5G advanced network. T-Mobile is rolling out its first network-native AI application, live translation, which uses language learning models embedded in its core. Furthermore, a partnership with Figure AI will connect T-Mobile's 5G advanced network to F03 humanoid robots, exploring how the network can support the broader evolution of physical AI and edge inferencing, positioning the company for future 6G capabilities.

Broadband Leadership and Fiber Expansion

T-Mobile maintained its position as the fastest-growing ISP in America, adding over 0.5 million total broadband net additions in Q1, with 5G broadband net adds accelerating year-over-year. Its 5G broadband speeds are over 50% faster than the next closest competitor.

The company is expanding its fiber footprint through two new joint ventures to acquire GoNetSpeed, Greenlight Networks, and i3 Broadband, emphasizing a returns-focused, capital-efficient approach to create local equity value rather than chasing homes passed numbers.

Customer Experience and Retail Evolution

Customer experience remains a key differentiator, with the T Life app engaging 25 million monthly active users and serving as a unified platform for digital interactions and growth into adjacencies like financial services and advertising. The retail strategy is evolving towards 'experience stores,' which exhibit higher premium mix and NPS scores, leading to a future mix shift towards fewer but more impactful physical locations.

UScellular Integration Progress

The integration of UScellular is progressing well, with customer migration efforts now in their final stages. The company expects to substantially complete the integration by the end of the current year. This integration is bolstering T-Mobile's network advantage in smaller and rural markets, leveraging past experience from the Sprint integration to ensure a smooth transition for the approximately 4 million UScellular customers.
